The Trane VAL2370 is a heavy-duty 2-ton thermostatic expansion valve engineered for precision refrigerant metering in residential and light commercial HVAC units. Featuring a 3/8" x 1/2" ODF connection, this external equalized TXV is designed to maintain optimal superheat across the evaporator coil, preventing liquid slugging and protecting the compressor from premature failure. Built with a rugged brass body and stainless steel internal components, the Trane VAL2370 TXV is rated for a maximum operating pressure of 450 PSI, making it fully compatible with high-pressure R-410A refrigeration systems as well as legacy R-22 and R-407C setups. This OEM Trane replacement part ensures seamless integration with factory specifications, providing the reliable flow control necessary to restore system efficiency and cooling capacity. For technicians performing a tear-down or coil swap, this valve offers the mechanical consistency required for demanding field environments. Key Benefits Optimized System Efficiency: Maintains precise refrigerant flow control to maximize heat transfer across the evaporator. Compressor Protection: Regulates superheat to prevent liquid refrigerant from returning to the HVAC compressor. Durable Construction: High-grade brass and stainless steel design withstands 450 PSI operating environments. Broad Compatibility: Standard 3/8" inlet and 1/2" outlet sizing fits a wide range of Trane and American Standard air handlers and heat pumps. Common Questions Is the Trane VAL2370 compatible with R-410A? Yes, this valve is rated for 450 PSI, making it suitable for R-410A, R-407C, and R-22 systems requiring a 2-ton capacity. Does this TXV include an external equalizer? Yes, the Trane VAL2370 features an external equalizer line to accurately monitor pressure at the evaporator outlet for better superheat management. Can this valve replace a 1.5-ton or 2.5-ton valve? No, this is a fixed 2-ton TXV. Using an improperly sized expansion valve can lead to hunting, evaporator freezing, or compressor damage.
